The development comes after the West Bengal government on Saturday claimed it had given clearance to eight trains to be run carrying its migrant home. Four of these trains, it said, were to depart on Saturday, which did not.

On the other hand, the railway officials said that the national transporter has a capacity to run around 300 trains per day ferrying around 20 lakh migrants in a maximum of five days.

The railway officials, however, said that the clearances from states are not forthcoming, especially from states like West Bengal and Rajasthan, which till now have accepted the least number of such trains despite being a significant source of the migrant population.

As per updates, a total of 366 Shramik Special trains have been operationalised across the country, of which 287 had reached their destinations and 79 trains are in transit.
